The Docs


Dr. Carla Irven (Smith), DC

Dr. Irven began her chiropractic education knowing she would one day practice in Colorado. Her dream came true when she met Loveland native Dr. John Smith while attending Palmer College of Chiropractic Florida. After both receiving their degree as Doctors of Chiropractic, they moved to Loveland and got married. Together, with Dr. Smith, they opened Rocky Mountain Spine & Disc in Fort Collins. Dr. Irven and Dr. Smith are the proud parents of three dogs and a cat; they enjoy an active life skiing, hiking and camping with their dogs.

Dr. Irven is certified in Animal Chiropractic by the Animal Chiropractic Certification Commission of the Animal Veterinary Chiropractic Association and completed here post-graduate education in the Animal Chiropractic Program at Parker College of Chiropractic in Dallas, TX. Prior to a career in Chiropractic, Dr. Irven began a career working with animals by living with exotics on an animal sanctuary in Arizona as a keeper of big cats, wolves, mountain lions and other exotics. She became a Licensed Veterinary Technician and began working in veterinary medicine. She worked with domestic animals in emergency, reproductive and nuclear medicine, and with horses in an equine practice in Las Vegas, Nevada.

Dr. Irven is also a Certified Medical Examiner for the Department of Transportation and a Certified Practitioner of the Personal Injury Institute. She is trained in Activator Methods I & II, Graston Technique and has post-graduate training in Nutrition, Extremity Adjusting, Whiplash and Brain Traumatology.

While she loves working with animals again, she remains fully dedicated to her human patients and to helping you live the type of life you were meant to be living! She believes that growing older shouldn’t have to mean growing sicker.
